COMPOSITION AND STABILITY OF SOME METAL-5-SULPHOSALICYLATE COMPLEXES
The 5-sulfosalicylate complexes of Al(III), Cr(III), U(VI), Ni(II), Co(II), and Mn(II), were investigated by the potentiometric method. The Al(III)- and U(VI)-5sulfosalicylate systems were investigated spectrophotometrically. It was found that Al(II) forms 1: l, 1: 2, and 1:3 complexes at pH values of 3.8, 5.5, and 8.5, respectively, and that U(VI) forms 1: 1 and 1: 2 complexes at pH values of 4.5 and 7.5, respectively. The stability constants for Be(II)- and Cu(II)-5-sulfosalcylate complexes were recalculated. The log k values found by the potentiometric method for the step-wise stability constants are as follows: Al, 13.20, 9.63, 6.06; Cr, 9.56; U, 11.14, 8.06; Ni, and Cu, 9.52, 6.93. (auth)
